4 Benefits of Using Gas Detector Tubes

When sourcing gas detectors, it can be confusing. What measures my target gas? Will I need training? Can it be used in an explosive atmosphere? Then there’s the problem of trying to find a solution within your price range.

With gas detection tubes, that process is simple...

Gas detector tubes are easy to use, are low cost, and the method is intrinsically safe, allowing them to be deployed easily. Because gas detector tubes don’t require calibration, users see the benefits of this technology over electronic gas detectors due to their ease of use.


  1. Not sure which gases to monitor? No problem

Gas detector tubes are perfect for any newcomers to gas detection or for those who are looking for a cost-effective solution to gas detection where they don't know which hazardous gases are present.

The Polytec multi-contaminant detector tube that quickly identifies present gases. This gives you greater insight into what is in the environment so when you know which gas you are looking for; you can confidently buy the correct detector tube for ongoing analysis.


  1. Measure Exotic Gases Cost-Effectively

The gas detector tube system is a complete sampling and analysis system for determining levels of exotic gases concentrations quickly and easily.

Whereas conventional gas detectors tend to be used to measure standard gases e.g. Carbon Monoxide, Hydrogen Sulphide, Sulphur Dioxide etc, the detection of exotic gases e.g Mercaptans or Acetaldehyde can be costly due to the more specialist detection technology required such as PID.

PID detection is used to provide a total VOC reading. As an alternative to PID, gas detector tubes can be used to specify the individual VOC gases that a PID detects.


  1. No Oxygen Required

For 99% of the detector tubes, there is no oxygen needed for conducting a measurement. This allows measurement into tanks, wells, manholes, etc. where minimal oxygen is present. Here, you can think about measuring H2S, NH3, and CO2 for safety detection or process analysing.


  1. Low-cost gas detection

Following the initial one-off outlay of purchasing an air sampling pump for about £185, the only ongoing consumable cost is for the glass gas tubes. The gas detector tubes are low cost with a pack of 10 tubes costing less than £30.

With no calibration required, there are no on-going costs associated with detector tubes.

Look out for suppliers that offer detection tubes at one consistent price which makes it easier for procurement processes.


What are Gastec gas detector tubes?

Gastec tubes are single-gas, single-use tubes which form a catalogue capable of measuring around 300 hazardous and toxic gases, and chemical vapours.

Most activities that the detector tube system is used for is to perform field screening and carry out spot sampling e.g. to determine the level of hazardous gases present on-site.

Whether that is in a confined space or near to where there is likely to be a build-up of chemicals, gas detector tubes measure the present levels at that moment in time.
